Pull MTD updates from Miquel Raynal:
 "A big core MTD change is the introduction of a new class to always
  register a master device. This is a problem that has been there
  forever: the "master" device was not always present depending on a
  number of heuristics such as the presence of fixed partitions and the
  absence of a Kconfig symbol to force its presence. This was a problem
  for runtime PM operations which might not have the "master" device
  available in all situation.

  The SPI NAND subsystem has seen the introduction of DTR operations
  (the equivalent of DDR transfers), which involved quite a few
  preparation patches for clarifying macro names.

  In the raw NAND subsystem, the brcmnand driver has been "fixed" for
  old legacy SoCs with an update of the ->exec_op() hook, there has been
  the introduction of a new controller driver named Loongson-1, and the
  Qualcomm driver has received quite a few misc fixes as well as a new
  compatible.

  Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP
  table fixups for Macronix MX25L3255E have been merged.

  Aside from this, there is the usual load of misc improvement, fixes,
  and yaml conversion"
